Locking swivel apparatus

ABSTRACT

A unified swivel snap device provides optional rotational motion for use as fishing tackle to couple lures, bait hooks, and weights to a main fishing line. Embodiments include a rod rotatably held within a housing and a snap configured to lock the swivel by attaching to both the housing and the rod. Embodiments of the swivel can be unlocked by attaching the snap to the rod alone and allowing the rod to swivel relative to the housing. The swivel snap can be used for enhancing a variety of fishing mechanisms including the shank of jigs and the spindle of lures and other apparatus attached to fishing lines. Embodiments of the locking swivel snap can be used in other applications which call for selective locking of swivel motion.

BACKGROUND

1. Field of the Invention

This invention relates to locking swivel apparati. In some embodiments, the locking swivel apparati may be used in fishing to fasten terminal gear to a main line.

2. Description of the Related Art

In some embodiments, the locking swivel apparati of the invention may be used for fishing. The practice of fishing typically entails use of a rigid snap connector at the end of a primary line. Such snap connectors are generally devices for attaching fishing lines by a wire snap or clip. These wire snaps are generally small closeable wire structures with an openable loop for attaching gear to the end of a primary line. For example, devices such as double end locking wire snaps, twisted wire hook closures with eyelets, and devices with dual locking arms with eyelets have been used for some time.

In many situations a swivel body can also be used in attachment of lines. Such swivel bodies generally comprise an upper end to which a main line can be attached, and a lower end configured to rotate relative to the upper end. Terminal gear can then be connected to the lower end of the swivel by a wire snap in order to allow the terminal gear to rotate without twisting the main line.

Anglers on larger rivers and lakes frequently fish for various species in varying water depths with a variety of fabricated spoons, lures, bottom bouncers, weights, and natural bait hook arrangements. Many of these devices function correctly with only a non-swiveling snap connector to the line, while others also require a swivel to avoid twisting of the gear or the line and to provide proper action for the hook assembly. Many existing swivel devices also include a snap. However, one must remove the entire assembly in order to replace it with a snap when a non-swiveling snap is desired.

SUMMARY OF THE INVENTION

Therefore, it is desirable to integrate the functions of a swivel and a non-swiveling snap into a single device. Thus, embodiments of the present invention bridge the arts of non-swiveling snaps and swivel bodies by integrating swivel and snap functions into a unified device which includes a locking mechanism that can be adjusted by the operator to select either the non-swiveling snap alone, or the swivel and snap functions together.

Accordingly, some embodiments of the present invention provide a new fishing tackle wherein the action of a swivel can be manually engaged or disengaged using an integrated snap fastener. Such embodiments of the invention advantageously provide simplified means to meet design criteria in the use of terminal gear to enhance varied fishing techniques. Embodiments of the invention also reduce the risk and difficulties inherent in cutting and retying lines to individual snaps, swivels, or traditional swivel snap combinations, and also reduce the amount and variety of attachment hardware in an angler's tackle box, and the frequency of need to access such storage.

Embodiments of the invention advantageously integrate the option for swivel action with the provision of a snap closure to which all types of hooks and lures can be easily fastened and effectively deployed to meet their design capabilities. By combining a traditional snap connector with an optional swivel, embodiments of the present device facilitate a wide array of fishing techniques without the common difficulties of cutting and retying lines to individual snaps, swivels, or traditional swivel snap combinations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of a universal swivel snap device generally include a housing (1) having an open lower end (22) through which a rod (3) extends and an upper end (24) from which an eye (2) extends. The rod (3) comprises apertures (9) generally configured to receive a clip or wire snap (30). The rod (3) is also generally configured to be at least rotationally (and in some embodiments both axially and rotationally) movable relative to the housing (1). In some embodiments, the housing (1) also includes apertures (6) configured to be aligned with the apertures (9) of the rod (3) such that a wire snap (30) can be inserted through the housing apertures (6) and through the rod apertures (9), thereby substantially limiting the ability of the rod (3) to rotate relative to the housing (1).

With reference to FIG. 1, the illustrated device includes a housing section (1) with a static post or stud with an eye (2) on an upper (lead) end (24) and an opening on the lower (trailing) end (22) from which a rod or dowel (3) extends.

In some embodiments, the housing (1) can be substantially cylindrical in shape, and can be formed by assembling first (20 a) and second (20 b) housing parts. The first (20 a) and second (20 b) housing parts can be secured to one another by a press fit, adhesives, threads, or any other suitable attachment means. A cylindrical housing (1) can be provided in the approximate proportion of one-to-three, width to length. In one embodiment the upper two-thirds (4) of the housing including the static stud eye (2) can be preformed and press fit over the lower one-third (5) of the housing that itself can be preformed with two lateral apertures (6) on opposing sides of the housing (1). Thus, in some embodiments, the housing (1) forms a cavity possessing a ridge (7) along the internal circumference of the seam of the joined housing halves (e.g. see FIGS. 2A and 2B). Alternative constructions are also possible. For example, the housing can be formed as a single piece having a hinge joint. Alternatively, the housing can be formed in a one-piece construction, and a rod (3) can be configured to be inserted through a lower aperture of the housing (1).

In some embodiments, the housing apertures (6) can comprise holes in the housing sidewalls. For example, the apertures can comprise elliptical holes (6 a) as illustrated in FIG. 1. Alternatively, the apertures can comprise circular (6 b) (see FIG. 12) or otherwise shaped holes as desired. In an alternative embodiment, illustrated for example in FIG. 3, the apertures (6) can comprise arcuate scallops (6 c) in a lower surface (22). In the embodiment of FIG. 3, the upper rod aperture (9) is located such that a snap inserted therethrough will engage the arcuate scallops (6 c) of the housing in order to lock the rod (3) against rotation.

With reference to FIGS. 4A and 4B, in embodiments in which the device is used for fishing, a means for connecting lures, hooks and weights can be a wire loop combination retainer and snap (32) configured with locking arms (11). FIG. 4A depicts such a snap (32) in an open position, and FIG. 4B depicts snap (32) in a closed position. The snap (32) is typically constructed from a metallic material of suitable length and spring force to form two spring loops drawn into interdependent locking positions. The angularity at critical points of radii (e.g. 12) can be configured to pass through the housing apertures (6, 6 a, 6 b, and 6 c) and the rod apertures (9, 9 a and 9 b). The retainer loop end (10) is generally configured to be inserted through the aperture (9, 9 a and 9 b) of the rod below (3) the housing (1) and locked as in FIG. 2A and FIG. 3. Alternatively, the retainer loop end (10) can be configured to be inserted through the collateral apertures (6) of the housing (1) and the rod (3), thereby locking the swivel apparatus as shown in FIG. 2B. The snap loop end (13) of a wire loop combination retainer and snap closure (32) can be pendently hinged at either position on said housing for attachment of terminal gear as shown, for example in FIG. 5. Alternatively, any clip, wire snap, link, or any other suitable device known to the skilled artisan can be used in place of the illustrated snap (32).

As shown in the embodiment of FIGS. 2A and 2B, the rod (3) can be a swivel shaft with a head (8) held in the housing (1) to rotate freely on a bearing ridge (7) formed by coupling cylindrical housing parts (20 a, 20 b). Alternatively, as shown in FIG. 6, the head can rotate on one or more ball bearings (34) in the housing with a rod (3) extending therefrom. According to the embodiment of FIG. 6, a bearing surface between the head and the housing is a raceway.

FIG. 7 is an exploded view of an embodiment similar to that discussed with respect to FIG. 6. The retainer end (10) of the snap (32) is configured to engage the arcuate scallops (6 c) in an open lower end (22) of a second housing part (20 b), such that rotational movement of the second housing part (20 b) relative to the snap (32) is impaired when the retainer end (10) engages arcuate scallops (6 c). When assembled, the second housing part (20 b) will be secured to a first housing part (20 a) by any suitable attachment means previously discussed, forming a housing which surrounds a head (8) of a rod (3). Rod (3) further comprises rod apertures (9 a) and (9 b), which are configured such that the snap (32) is insertable through either of the apertures (9 a, 9 b). Located below the head (8) of rod (3) are ball bearings (34), which enable easier rotational movement of rod (3) relative to the assembled housing. First housing part 20(a) comprises an eye (2) within a static post on an upper end (24), which can be used to secure the assembly to, for example, ring (50).

FIG. 8 is a cross-sectional view of the assembled housing and rod of the embodiment of FIG. 7. It can be seen that the interior of the assembled housing (1), formed by securing first housing part (20 a) to second housing part (20 b), contains the head (8) of rod (3), under which sit ball bearings (34). It can be seen that, in certain embodiments, the shape of the interior cavity (52) may prevent significant axial translation of rod (3) relative to housing (1).

Now with respect to FIGS. 9A and 9B, assembled views of the embodiment of FIG. 7 are depicted. In FIG. 9B, it can be seen that arcuate scallop (6 c) is aligned with rod aperture (9 a), and that the retainer end (10) of the snap (32) has been inserted through aperture (9 a) and has engaged arcuate scallop (6 c), inhibiting axial rotation of the rod (3) relative to assembled housing (1). In alternate embodiments, axial translation of the rod relative to housing (1) is to some degree not inhibited by the design of the interior cavity of the housing (1) and the design of the rod (3). In such embodiments, it can be seen that the engagement of the snap (32) with arcuate scallop (6 c) and aperture 9 a will inhibit axial translation of the rod (3) toward the assembled housing (1).

FIGS. 10A and 10B depict the embodiment of FIG. 7 in an assembled and unlocked position. In FIG. 10A, it can be seen that the retainer end (10) of the snap (32) has been inserted through aperture (9 b), such that arcute scallop (6 c) is not engaged. Thus, axial rotation of rod (3) relative to assembled housing (1) is not inhibited.

In another alternative embodiment, as illustrated for example in FIG. 11, the head can comprise a spherical ball (8′) (e.g. a ball bearing) with a rod (3) extending therefrom. According to this embodiment, a bearing surface between the head (8′) and the housing can be substantially semi-cylindrical. A rod (3) can be inserted (e.g. press fit, threaded, etc) into a hole in the ball-shaped head (8′), or the rod (3) and ball (8′) can be formed as a unitary structure, such as by molding or machining.

In some embodiments, the swivel shaft can be perforated with a slotted aperture (9 a), such as that shown in FIGS. 2A, 2B and 5. A slotted aperture (9 a) can be utilized as shown in FIGS. 2A and 2B to allow a snap to be connected to the device in either the “locked” (FIG. 2B) or “unlocked” (FIG. 2A) position without the need for moving the rod axially within the housing. Alternatively, this advantage can be achieved by providing a plurality of holes in the rod (3) to allow for connection of the snap at various locations along the rod (3) (e.g. FIGS. 3, 5, 6).

In an alternative embodiment, as shown in FIG. 12, the rod (3) can be provided with a single circular aperture (9 b) and the rod (3) can be moved axially within the housing to align the rod aperture (9 b) with the housing apertures (6) to lock the device. Alternatively, the rod (3) can be positioned within the housing (1) such that the circular aperture (9 b) extends from the lower end (22) of the housing to allow the device to be used in an unlocked position. Alternatively still, the rod (3) can be configured to retract entirely within the housing (1) to allow a snap (30) to be connected to the housing without extending through the rod aperture (9 b) as shown in FIG. 4. A cylindrical housing (1) according to this alternative embodiment can be provided in the approximate proportion of one-to-four, width to length, although other ratios can also be used.

In further alternative embodiments the rotational motion of the swivel can be provided for by any suitable swivel device including various types or constructions of a shaft within a tubular skeleton or the equivalents thereof and thereby providing surfaces of reduced friction facilitating rotary motion wherein the rotational motion of the swivel can be locked to affect attached tools.

The rod apertures (9, 9 a and 9 b) can be configured such that the retainer end (10) of a wire loop combination retainer and snap (such as that shown in FIGS. 4A and 4B) can be inserted therein at optional positions either through the cylindrical housing and rod (e.g. as shown in FIG. 2B) to arrest rotation and retain only the snap function, or below the cylindrical housing (e.g. as shown in FIG. 2A), for both swivel and snap functions.

FIG. 13 illustrates still another alternative embodiment in which the housing apertures include slots (40). In the embodiment of FIG. 13, the rod (3) can include a single circular aperture (9 b) and a slot (40) can include a locking section (42). If desired, a spring (44) can be positioned within the housing (1) between the head (8) and an upper inner surface of the housing to bias the head (8) and rod (3) downwards. Thus, in the position shown, the swivel is free to rotate. The swivel illustrated in FIG. 13 can be locked by moving the rod (3) and snap (30) upwards within the slot (40), then rotating the rod (3) and snap (30) to the locking section (42) of the slot (40). The rod (3) and snap (30) can then be released and the spring (44) can retain the snap (30) in the locking section (42) of the slot (40). In still further embodiments, slots of other shape, size, etc. can also be used to lock the swivel.

In further alternative embodiments, the rotational motion of the swivel can be locked with transverse pins such as a set screw, a pressure activated push-pin located on the swivel housing, spring-loaded pins, or other clips, clamps, cotter pins, hitch pins, hair pins, etc. Such alternative pins, screws, clips, clamps etc. can be any type or construction recognized as suitable for locking a rotational motion of the rod relative to the housing. Mechanisms other than pins may also be employed to prevent the rotational motion of the swivel such as a threaded nut on a threaded swivel rod (as shown for example in FIG. 14).

While embodiments of the present invention have been discussed primarily with relation to the use of a locking swivel in connection with fishing equipment, it will be apparent that embodiments of the invention can be utilized for a wide range of purposes, with locking swivel devices having a wide range of sizes and designs.

Suspension of items on swivel hooks is a useful technique in factories and other locations where persons working on those items need access to various sides of a given item. For instance, in the meat-cutting industry, swivel hooks are used to suspend carcasses and convey them through a meat cutting plant. While the rotational freedom provided by the swivel hook is desirable so that a worker can orient the suspended item in any way needed, it may be desirable for both safety and productivity reasons to provide a way of inhibiting the rotation of the suspended item. Such inhibition can be used, for instance, to prevent rotation of a bulky item as it moves through a factory, or to maintain a particular orientation of a device

A heavy-duty locking swivel similar to the embodiments previously discussed can be employed in such a situation to provide an easy method for such a worker to inhibit rotation of such a swivel hook. Any method of inhibiting rotation discussed above can be employed, including but not limited to the use of a set screw, a removable pin or a spring loaded pin. Certain modifications to the embodiments discussed above may be desirable, such as the inclusion of multiple apertures or arcute scallops arranged at various positions around the housing, in order to enable the locking of the rod and suspended item into various rotational positions when a pin or other item extending through the rod is used to inhibit rotation.

Embodiments of the present invention may also be used in a variety of household tools, where it may be desirable to have a tool which can be easily switched between a rotatable state and a locked state. For instance, a window cleaning device could be constructed having a cleaning end which can be made rotatable relative to the handle. Such a design would be particularly advantageous in a device which can employ multiple cleaning attachments, certain of which require that the handle be rotatable with respect to the attachment, and certain of which require that the handle be fixed relative to the attachment.

In addition, while many of the embodiments discussed above utilize a solid body which extends completely through the rod, it will be apparent to one having ordinary skill in the art that many of the above discussed embodiments may be modified to include a solid body which extends, for example, through a single aperture in the housing and only partially into the rod.

Although certain embodiments and examples have been described herein, it will be understood by those skilled in the art that many aspects of the methods and devices shown and described in the present disclosure may be differently combined and/or modified to form still further embodiments. Additionally, it will be recognized that the methods described herein may be practiced using any device suitable for performing the recited steps. For example, in some embodiments, the swivel can be operated in an inverted orientation relative to the orientation shown in the attached figures (i.e. the housing could be positioned vertically below the rod). Such alternative embodiments and/or uses of the methods and devices described above and obvious modifications and equivalents thereof are intended to be within the scope of the present disclosure. Thus, it is intended that the scope of the present invention should not be limited by the particular embodiments described above, but should be determined only by a fair reading of the claims that follow.
